First Draft is compatible with Windows operating systems from 98 to 7. Because the developer doesn't have access to Windows 8, Windows 8.1 or Windows 10, the software's functionality on those systems is unknown. However, a few users have indicated that it "works funny" on Win 8, if at all. If you have a Windows 8, Windows 8.1 or Windows 10 machine, and you experience problems with First Draft, the following may help.
Run First Draft as an Administrator
First Draft needs to write and read files to a computer's hard drive, but because of Windows strict (and sometimes unnecessary) security protections, the software won't function the way that it's programmed to function. Running it as an Administrator may help.
If that sounds like something you'd like to try, head on over to the Eight Forums website for a great tutorial that explains how to run any program (including First Draft) as an Administrator.
Make First Draft Compatible with Win 8 & Win 10
An alternative approach is to make (force) First Draft's compatibility. At the Microsoft website, you'll find some documentation that explains how to use the Program Compatibility Troubleshooter and how to Change Compatibility Settings Manually if necessary.
Install First Draft on the C:\ Drive (NOT in the Programs Folder)
Some people have reported First Draft works just fine when it's installed into its own folder on the C:\ drive -- NOT in the Programs Folder. So give that a try as well.
